I am very new to Blackberry so I was so anxious when I got my unlocked Blackberry 8310. I went and updated the OS from 4.22 to 4.5 and now my Blackberry is dead. The only thing that is working is the led on the top that is flashing red. I can't send it back to the store I bought it from cause I live in Barbados and the phone came from the USA.
